IMPROVEMENT IN WINDMILLS.

Specification forming part of Letters Patent No. 175,670, dated April 4,1876; application filed September 7, 1875.

To all whom it may concern:

Be it known that we, GILES GRAMTON and ELIJAH L. CORIELL, of Marshall,Michigan, have invented a new and useful Improvement in Windmills, ofwhich the following is a full and accurate description, reference beinghad to the accompanying drawing.

Like letters on'the different figures refer to Figure 1 is a side Viewof the mill. Fig. 2 is a rear view of one of its sections.

Our invention relates to the rods connecting the sections to theslide-head in that class of mills in which the sections are so hinged asto turn out at right angles to the plane of the wheel upon an axis inthe plane of the wheel, and at right angles to'the radius through thecenter of the section.

The manner of hanging the sections is shown in Fig. 2.

At each end of the bar 11 is a suitable journal, turning in bearings c 0near the ends of the arms J J of the wheel. Near the ends of the bar I)are short arms 00 a", projecting inward toward the center of the wheel.To the ends of these arms .70 w are hinged the ends of the connectingrods a a. These two rods are brought together and hinged at one point,n, in one of the slots 2; v in the slide-head d.

It is immaterial whether the two rods are united in one piece at n, orare hinged separately to one point on the slide-head. The main point isto form the triangular arrangement of the rods a a and bar I), so as tomake the connection between the section A and slide-head d rigidlaterally, and avoid the necessity of using a square main shaft orgroove and key to prevent the tendency of the slidehead to turn on theshaft.

Small weights 9 g are attached, by short arms, to the front of thesections. These weights tend to turn the sections out, approaching theposition shown by the dotted lines,when the wheel is in motion. Thistendency is opposed by the weight K on the bent lever to through the rodh, slide'head (l, and connecting-rods a a, thus making it aself-regulating wheel.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, isp In a windmill, the triangular arrangementof the rods a a, to form a connection between the sections and theslide-head, substantially as and for the purpose shown and described.
